SkyMax Energy Legacy PMG

Assembled and supported in the USA, our Legacy and Frontier Wind Turbine PMGs are now designed with a keyed shaft and hub stabilizer as well as includes a self-tightening cam-lock washer to prevent the blade set from ever spinning on the shaft.

Operating Information:

1. Produces battery voltage at approximately 266 RPM
2. Produces twice (2X) the battery voltage at approximately 506 RPM
3. Produces four times (4X) the battery voltage at approximately 960 RPM

For wind turbine use only. For hydro, gas engine, and electric motor coupled use, see our Hydro PMG.

Why buy a Legacy or Frontier PMG over a Delco car alternator PMA?

The answer is simply more copper! More copper equals more power - each Legacy PMG stator contains twice as much copper than any Delco style PMA.

Additional reasons why the Legacy PMG is better than ANY Delco or other modified car alternator PMA:

• Some modified alternators use power to make power. Skymax Legacy PMGs use no input power.
• PMAs use a thin aluminum housing and the stator is not pressed in. The Legacy PMG
• features a very thick aluminum housing with additional cooling fins and a pressed in stator that helps with proper alignment and durability.
• PMAs have only two mounting holes. The Legacy PMG has four of them bolted tightly against the mounting bracket for secure mounting.
• Alternators and some PMAs have a weak rear bearing that wears quickly. The Legacy PMG utilizes two large heavy duty bearings to prevent heat build up and premature failure.
• Most car alternators and PMAs that are repurposed use low grade/high iron electrical steel which can create a lot of heat. The Legacy PMG uses high grade electrical steel that is optimized for efficient cooling.
